MigX - Conditions: only build output, if MigX isnot empty

I want two different outputs, one for the case the MigX TV is not empty and another for the situation the MigX TV is empty.

So i build up the following getResource-Code:

[[getResources?
&parents=`17`
&tpl=`footer-projekte-tpl`
&includeContent=`1`
&includeTVs=`1`
&processTVs=`1`
&depth=`0`
&limit=`6`
&showUnpublished=`0`
&showHidden=`1`
&sortby=`{"menuindex":"ASC"}`
]]

And the following footer-projekte-tpl (better code-solutions related to the input/output filters are welcome):

[[*migx-projekt-items:isnot=``:then=`
<li>
    <a href="[[!++site_url]][[*uri]]" title="Projekt [[+longtitle]]">
        [[+longtitle]]
    </a>
</li>
`]] 
[[*migx-projekt-items:is=``:then=`
<li class="grey">
    [[+longtitle]]
</li>
`]]

But that does not work. I always get the second output without any link, although on some sites/projects the migx is filled in (and others are not). Can I make such a condition, to relate it to a migx TV? Help

You could try it using the :else=`` in the first output modifier, instead of using two output modifiers. Also be careful, you're using resource TV tags [[*...]] where you should probably be using placeholder tags [[+...]]

See an explanation here http://modxcookbook.com/add-ons/menus/ (this applies to any listing snippets that use tpls).

Ok, changed the tags to placeholder tags. Thx. Now i've added the :else ...but it does not change anything in the output, though it's a nicer code. Still only get no links.

Important: the "[[+migx-projekt-items]]" is no normal tv used in any migx - but it is a migx tv itself. Can i relate any condition to a migx-tv? And also: i have no getImageList anywhere related to this chunk-tpl.. so maybe the chunk does not even know what "[[+migx-projekt-items]]" is?

Maybe can i tell "getresource" to include migx(Tvs)?

Now that made my head hurt!

getImageList is used to output the list of items in a MIGX TV.

If you have MIGX TVs for each of the resources listed in your getResources call, then you'd need a getImageList in the getResources chunk tpl.

But I can't figure out what exactly you have and what you are trying to do with it.

Okay, i just noticed, there must be a big fault.

The situation: I have project resources/sites in my resource tree. These projects have the migx TV contained. If the migx TV is not empty for one resource, i want these project named in the footer with a link to it. But if the migx is empty, it should also be mentioned - but without any link to the project site.

So i thought to relate this condition to the migx tv - if it is empty for the resource or not. But the getImageList is only on the project site. I have no getImageList for the footer (that is on every site, not only on project sites), for example.

It is soo complex and complicated for me as a beginner.

A MIGX TV stores its data as a JSON string in the same field that any TV stores its value.

So this should work:

[[+migx-projekt-items:isnot=``:then=`
<li>
    <a href="[[!++site_url]][[+uri]]" title="Projekt [[+longtitle]]">
        [[+longtitle]]
    </a>
</li>
`:else=`
<li class="grey">
    [[+longtitle]]
</li>
`]]

That does not work. But any other TV does not work, too. I don't understand why.
It works, when i relate it to "+hidemenu":

[[+hidemenu:isnot=``:then=`
<li class="grey">
    [[+longtitle]]
</li>
`:else=`
<li>
    <a href="[[!++site_url]][[+uri]]" title="">
        [[+longtitle]]
    </a>
</li>
`]]

But it does not work, when i relate it to any tv like a new tv called [[+hiddenInFooter]]. Though i have the options "includeTVs" in the getresource call (as in the first post).

I would need to see what you have in order to do any more. I'm just guessing since I don't know what you have.

Omg, of course! That's it bruno. And now it also works with the migx-tv itself.
Thank you both!!
